I am having RAM memory related issues while trying to execute a modal-spectral analysis. Using lower order elements or thickening the mesh it is not an option. I “only” have to reduce the RAM requirements of the analysis in 2.6Gb aprox (from 33.5Gb to 31.9) so out-of-core solving is possible (not even thinking about in-core solving).<\/p>\n
Its remarkable that I dont have RAM related errors while running structural analysis with the same exact model. Thats why I think there might be an option to reduce analysis RAM requirements for the modal-spectral analysis I am trying to execute. ChatGPT has given me the following solutions:
– Reduce the number of iterations
– Use a more efficient solver method
– Use lower precision settings
– Explore the memory optimization settings
– Reduce the amount data written to output files
– Use solver-specific options to control memory usage
– Run the simulation in batch mode without the graphical interface.<\/p>\n
Sincerely, I dont know how to implement any of these option, as I am a relatively new user of Ansys and I am experimenting my first RAM issues. In fact, I dont even know if any of these solutions will be helpful for my problem. I would realy appreciate some advice from more experienced users. Thank you in advance.<\/p>\n","protected":false},"template":"","class_list":["post-317639","topic","type-topic","status-closed","hentry","topic-tag-low-memory-2","topic-tag-memory-error","topic-tag-ram-1"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
